MACHINE FOR SHAPING nrrnlts ovnn'LAs'rs.

Application filed March 16, 1923, Serial No. 625,592. Renewed February2, 1927.

This invention relates to machines for use inthe manufacture of bootsand shoes for shaping the upper materials, and is herein illustrated inits application to a well known 6 type of bed lasting machine and moreparticularly as applied to means for shaping the toe portion of theupper materials. It will be recognized, however, that in many of itsaspects the invention is not limited to a machine of the type shown norrestrictedto theshaping of the toe end of the upper.

'In one important aspect the invention relates to the positioning oflasting mechanism in relation to the shoe, and a feature of theinvention consists of a novel organization of power-operated mechanismfor effecting relative movement of lasting mechanism and a shoe withmeans for controlling said power mechanism as determined by eachparticular shoe. The machine herein shown comprises power-operated meansfor effecting in a predetermined manner relative movement of a shoesupport and lasting mechanism heightwise of the'shoe to accomplish whatis usuallytermed theupwiping of the upper and relative movementthereafter to wipe the upper inwardly over the bottom of the shoe, andincludes in its organization a device controlled by engagement with thebottom of the shoe for set ting the power driven parts in such'a manneras to insurethe termination of'the upwiping operation with the lastingmechanism in proper position for'the overwiping operation without lossof control of the upper.

In accordance with a further feature, the invention provides means forinsuring that the lasting; mechanism will operate uniformly on differentshoes, the construction shown comprising means for bringingthe wipersinto engagement with the shoe at the same predetermined distance fromthe plane of the shoe bottom in operating on different i shoes. Whilethis feature of the invention is not limited to a power-operatedorganization, it has important advantages in a machine where the wipersare closed automatically about the toe at a. predetermined time in thecycle to effect the upwiping operation, since it insures that the wiperswill not enthe shoe so far from the plane ofthe shoe bottom as tointerefere with their proper conforming action in the relative upwipingmovement of the shoe and the wipers. In the illustrated embodiment ofthe invention regulation of the extent of the upwiping, together withthe proper positionmg otthe wipers at the end of the upwipingas-liereinbefore explained, are effected by cooperating mechanisms oneof which imparts to the wipers an invariable movement heightwise of theshoe in operating on different shoes while the other is adjustablyvariable as determined by the particular shoe to determine the distancefrom the plane of the shoe bottom at which the upwipmg operation beginsand consequently the positionof the wipers relatively to the plane ofthe shoe bottom at the end of the upwiping operation.

A further feature of the invention consists in novel organization inwhich lasting or wiping mechanism which is yieldable in response toresistance of the shoe before it is moved inwardly over the bottom ofthe shoe is differently controlled in such inward movement, theconstruction shown comprismg'spring means permitting the wipers to yieldin conformity tothe shoe in the up wiping operation together withlocking means which actsboth to prevent further yield and also toprevent reaction of the spring means in the overwiping operation. Thisfeature is herein illustrated in its application to wiper operatingmeans includin'g separate springs for controlling the advance and theclosing of the wipers, with looking devices associated with thedifferent springs to afford positive control as the wipers are advancedand closed over the bottom ofthe shoe. By thus preventing reaction ofthe spring means which controls engagement with the shoe in the upwipingoperation insurance is afforded that the wipers will not he suddenlyprojected over the bottom of the shoe or moved inwardly farther thanwould be desirable, for example in lasting a shoe of the welt type, andby eliminating further yield of the spring means in the overwipingoperation better control of the wipers is afforded to insure that theywill be moved inwardly the precise distance desired. While theconstruction shown thus combines both these advantages, it will berecognized that the invention is not limited to an organization in whichthe yielding means is controlled in the particular manner illustrated.

styles and sizes. In the construction shown the desired result isaccomplished by the provision of means for varying relatively theratesof the advancing and closing movements of the wipers. It is Wellunderstoodithat the amount of angular closing movement of end embracingwipers required to force them inwardly a given distance from the edge ofthe shoe bottom at the sides of the shoe, for the same amount ofadvancing movement lengthwise of the shoe, depends upon how nearly thesides of the shoe approach a parallel relation to the longitudinalmedian line of the shoe, a greater proportional amount of such closingmovement being required on narrow pointed toes than on comparativelyround toes. In the use of prior constructions having means for impartingto wipers predetermined advancing and closing movements it has beenpossible only to effect a rough approximation to conditions which aredesirable for the best results, and for wide variations of styles orshapes it has been necessary to substitute be readily adapted, forexample, to operate on welt shoes or McKay shoes.

A further feature of the invention con sists in novel means of controlto enable the operator to produce different results in the operation ofthe machine, the construction shown comprising means todeterminedifferent stopping positions of the operating mechanism,together with a manually operated controlling member which is movable todifferent positions to determine in which of the stopping positions themachine will cometo rest and also to determine how long the machine willoperate before it comes to r a stop. More particularly, the constructionillustrated provides for stopping the machine with the wipers locatedeither in the tion to the shoe.

between the difl'erenttrains of mechanism, the extent of movementrequired of either position which they occupy at the end of the upwipingmovement or in the position which they occupy when the upper is to befastened, for example by wiring or tacking, and further provides forsuch control that the machine may be made to operate through its entirecycle any selected number of times.

Still another feature consists in a novel construction and arrangementof means'for imparting operative movements to the lasting mechanism orwipers. In its embodiment of this feature the machine shown is providedwith separate and operatively independent trains of mechanism forimparting respectively to the wipers their advancing and closingmovements, such mechanism including power transmitting elements soconstructed as to maintain a continuous operativerelation to the wipersin different positions of the wipers which they-assume,

for example, as a result of their operative n'iovement heightwise oftheshoe or of adjustments to position them correctly in rela- By reasonof the relation of them to effect the proper operation of the wipers isnot affected in any degreeby the extent of movement of the other. Thisgreatly facilitates the design of the operat ing parts -or cams, permitsthe position of the wipers lengthwise of the shoe and their relation toeach other to be readily varied independently by adjustment of therespective trains of operating mechanism, and prevents the relation ofthe wipers to each other from being disturbed by any bodily yield of thewipers lengthwise of the shoe that may occur in the upwiping operation.I

The above and other features of the'invention, including various detailsof construction and novel combinations of parts, will now be moreparticularly described by reference to the accompanying drawings andpointed out in the claims.

The machine comprises generally a suitable lrame 20 upon which ismounted a shoe supporting jacl'; 22 and a toe rest 24 for an assembledlast and shoe in the position shown in dotted lines in Fig. 3. The heelseat 01' a shoe supported by the jack 22 is arranged to be lasted bysuitable mechanism indicated generally at 26. Power may be supplied tothe machine by means of a belt driving a pulley 28 (Fig. 1) which isarranged to run continuously and which is connected to the jackingmechanism by a suitable one-revolution clutch controlled by a knee lever(not shown). These parts may be, and illustrated as being, the same asparts more fully illustrated and described in Patents Nos. 1,018,477,granted Feb. .27,

1912; 1,390,755, granted Sept. 13, 1921; and 1,373,482, granted April 5,1921, all on applications of Matthias Brock. The jacking mechanism! isreleased, after a shoe has been lasted, in response to a secondoperation of the knee lever, as fully described in said patents.

Vipers 30 are arranged to be operated by powci drivcn connections,hereinafter de' scribed, lt'or upwiping and overwiping the toes ofshoesheld by the aboveedescribed jaclting mechanism. These wipers aresecured in carriers (Fig. (3) arranged to be moved angularly in a heador carrier 34, to close them about the end of a shoe, by pinions b6meshing with rack teeth formed on the ct ges oi the carriers. Thepinions 36 are operated by a pair of racks 38 engaging an equalizingpinion 40 mounted on a sliding rod or plunger 42.

The head 34 carrying the wipers and wiper carriers is integral with orsecured to an inner sleeve or plunger 44 surrounding the plunger 42, thesleeve 44 being longitudinally D'lUVflblG, to advance andretract thewipers, in an outer sleeve 46 which is formed as part 01 ahead 48pivotally mounted on a shaft 50 (Fig. 3). The head. 48 may be tiltedabout shaft 50 in alining the wipers with the bot tom of a shoe bymanipulating a handle 52 as described in the above-identified Brockpatents.

Shaft 50 is carried by a slide 54, which may be angularly adjusted on a.slide 58 about a vertical axis passing adjacent the toe rest bymanipulating a hand wheel 56, in such a manner as to turn the wipers in.a horizontal plane to aline them. with the median line of the forepartof the shoe. Slide 58, in turn, is mounted on a second slide 60 by avdovetail connection, for horizontal movement laterally of the machine,and is arranged to be automatically operated dur* ing the operation ofupwiping the shoe as described in said Patent No. 1,390,755. Slide 60and the parts carried thereby are ar- 'holddown against the shoe by alink 96 operi i ranged for adjustment longitudinally of the machine on ahead 62 carried by a Vertical slide (54, a hand wheel 66 being providedfor facilitating such adjustment.

The wipers 30 may be tilted about an axis 7 attending longitudinally ofthe machine, to aline them transversely with the shoe bottom, bymanipulating a handle 68 to turn a threaded bolt-70 carrying a travelingnut T2 connected by a link 74 with a shaft 76 seat- 7 ing in a recess inthe head 34.

The shoe is held clamped against toe rest 2-1 by a holddown 80' mountedon an arm 82 which in turn is carried by a sleeve 84. Sleeve 84 isarranged to swing about a re so duced central portion of an inner sleeve86 threaded on a vertically sliding rod 88 and arranged to be turned bya suitable handle 90 to adjust the position of the holddownby raising orlowering it relatively to rod 88. Sleeve 86 is held in adjusted positionbyengagement of a spring pawl 92 (Fig. 3) carried thereby with a ratchet94 mounted on rod 88. Rod 88 is operatedto lower the ated by a tr eadle98, which is. held down by a pawl and ratchet and which is releasedafter the shoe has been lasted by a push rod connected to the pawl andratchet and to the jacking mechanism, and also to a specialpawl-releasing device,as described in the said Brock patents.

A bracketllO is clamped on the lower end of rod 88 in predeterminedrelation to the position of holddown 80 and is formed with a verticalrecess which is T-shaped incross section and in which a rack block 112is mounted for vertical adjustment. As will be explained, rack block 112operates to vary the position of power driven connections for raisingand lowering slide 64 according to the verticalposition of holddown 80when clamped against a shoe, so that vertical movement of slide 64 inupwiping the shoe is limited in such a manner as to position the wipers30 in predetermined relation to the plane of the shoe bottom. Rack block112 is arranged to be adjusted vertically by a belt 114 threaded througha vertical re cess in said block and journaled at its lower 115 end inbracket 110 to prevent it from moving vertically relatively to thebracket. Bolt 114 is connected by a universal joint 116 to atelescopicshal't 118 which is connected to the vertical adjusting deviceoperated by 120 handle 52 for tilting wipers 30 about shaft 50. By thisarrangement adjustment of the wipers by manipulation of handle operatesthrough telescopic shaft 118 to raise or lower rackblock 112 in itsbracket 110 in 195 such a manner as to compensate for changes in thevertical position of the wipers due to such adjustment.

Each block 112 meshes with a sector 120 mounted on arock shaft 122 whichcarries Zea an arm 124 connected by a link 126 to an arm I 128. pinion180 meshing with a rack 132 formed on, or secured to, the lower end ofthe vertically 'moving slide 64. The pinion also meshes with a secondrack 134 which is stationary during the early portion of the operationof the machine. The lower end of arm 128 carries a sliding block or rollarranged for movement in a curved slot 136 of a cam operated lever 138,in such a manner that movement of rack block 112 in clamping theholddown against a shoe operates through arms 124 and 128 to change theeffective length of the lever without moving the pinion 130. Lever 138is arranged to rockabout a shaft 140 mounted in arms 142 and 144 (Figs.3 and carried by the machine irame. Then the lever is rocked about shaft140 by its cam, hereinafter described, it 01 erates through arm 128 tomove pinion 130 upwardly. The pinion rolls on rack 134, which is at thistime stationary, and therefore operates through rack 132 to move slide(34 and the parts carried thereby upwardly a variable distance accordingto the ell'ective length 01 lever 138 to position wipers 30 the samepredeter-' mined distance below the plane of the bot tom of each shoebefore the wipers are closed about the toe for the upwiping operation.Insurance is thus ailiorded that, what" ever may be the verticalposition of the toe,"

the wipers will not engage the shoe too far from the plane of the solefor the best results in the upwiping oi the upper materials.

Lever 138 is operated and continuously controlled by .a face or path camon one side of a cam member 146 (Figs. 3 and 4).

mounted on a cam shait't 148 journaled in arms 142 and 144 of themachine frame.

Cam shaft 148 is arranged to be driven,

under the control of the operator, "from pulley 28 by worm 150 (Figs. 1and 4) meshing with a worm wheel 152. The worm wheel is connected byspring pins 154 with one member 01, a Horton clutch 156, of well-knownconstruction, so that in case the machine jams the spring pins 154 willslip and the driving mechanism will not be injured. 'lVorm wheel 152 isloosely mounted on shaft 148 and only drives the shaft when it isconnected thereto by manipulation of the Horton clutch 156. This clutchis formed with two disks 158 (Figs. 2 and 4) secured together, one ofwhich is formed with a stop a or abutment to be engaged by a controller160 and the other of which is formed with two similar stops 5 and a orabutments to be engaged by a controller 162. Controllers 160 and 162 areof the type which is ordinarily used for controlling a Horton clutch,and are mounted on the ends or the longer arms of a 3-arm This armvcarries at one end a lever 164.. This lever is carried by a bracketextending from the machine frame and is operated by a link 166 connectedto a bell crank lever 168 loosely mounted on shaft 122, the bell cranklever being in turn connected by a link 170 with a 'treadle 172 (Figs. 1and 3). i r

This arrangement is such that when the treadle 172 is in its upperposition (in! which it is held by a suitable spring) the 3- arm lever164 is rocked so that the controller 162 will engage its disk 158 todisconnect the Horton clutch with the parts either in starting positionor in a dill'erent position, as hereinafter more fully explained,depending upon which of the two abutments b and c on the disk is engagedby the controller. On the other hand when treadle 172 is completelydepressed, the 3arm lever 164 is rocked in the opposite direction sothat controller 160 engages the abutment a on its disk 158 to disconnectthe clutch from cam shaft 148 with the parts of the machine in stillanother position. When treadle 172 is held in' an intermediate position,neither oi? the controllers 160, 162 en gages its disk 158, so that themechanism opcrated by cam shalt 148 repeats itsjcycle of operations overand over again until the operator either releases the treadle or com-'carries a cam roll running in a cam track 8' formed in one face of a cam184 mounted on cam shaft 148. Thus cam 184 imparts a. predetermineddownward movement to rack 134 through lever to move slide 64 and theparts carried thereby upwardly a predetermined distance, after thewipers 30 have preliminarily been positioned by lever 138. Lever 138 isat'this time held stationary by a dwell in its cam so that movement ofrack 134 turns pinion 130 to operate rack 132 to impart the desiredvertical movement to slide 64. By this operation of rack 134 theupwiping operation is effected and during the overwiping operation(hereinafter described) the rack is yieldingly moved in the oppositedirection through spring 182 to force the wipers first lightly and thenheavily against the wiped-over upper materials to iron them down againstthe shoe bottom.

The wipers 30 are advanced and closed by independently operableconnections driven from cam tracks in the faces of cams 146 and 184which operate on cam rolls carried by bell crank levers 190 and 192,loosely mounted on a shaft 194 carried by arms 142 and 144 of themachine frame. Levers 190 and 192 are connected to a pair ofplungers 196(Figs. 3 and 5) each of which is surrounded by a sleeve 198 which isoperated by its plunger 196 through a coil spring 200 confined between.a shoulder on plunger 196 and a bushing 202 threaded in the end ofsleeve 198. Each bushing 202 is formed with a knurled head 204 by meansof which it may be adjusted to vary the compression. of spring 200, anda lock nut 206 is provided for securing each bushing in adjusted position. Each plunger 196 carries lock nuts 208 (Fig. 5) arrangedto engagethe head 204 of the corresponding bushing to move sleeve 198 positivelytoward the left in Fig. 5 to a predetermined initial position to adjustthe wipers, as more fully hereinafter explained.

Sleeves 198 are formed with rack teeth to engage and drive pinions 210and 212 carried by vertical shafts journaled in arms 144 and 142 of themachine frame. These arms are extended downwardly to form a stationarycasing 214 in which sleeves 198 may slide, and in which housings forpinions 210 and 212 are formed. Pinion 210 is conneoted through itsvertical shaft by a universal joint to a vertical telescopic rock shaft216 and similarly pinion 212 is arranged to drive a telescopic rockshaft 218.

At its upper end rock shaft 218 is connected by a universal joint to arock shaft 219 journaled in a pair of arms 220 integral with or securedto the head 48 supporting wipers 30 and their operating. mechanism. Therock shaft 218 is formed in two relatively rotatable parts (Figs. 3 and6) the lower part carrying an arm 222 which seats against an arm 224carried by the upper part; and the rock shaft 219 has fast thereon atoothed segment 226. When arm 222 is rocked to the right in Fig. 6 itoperates segment 226 by direct engagement with arm When it is rocked tothe left in that.

figure it operates the segment through a coil spring 228 engaging anadjustable head 230 on a bolt 232 which passes loosely through openingsin arms 222 and 224 and T is formed with a fixed head to engage armSegment 226 is in driving engagement with a rack 234 carried by an armextending.

from a sleeve 236 surrounding a reduced portion formed on the sleeve 44which carries head 34. Thus head 34 is moved back and forth to advanceand retract wipers 30 by rock shaft 218 operating through rack andsegment 226 and 234. Sleeve 44- is free to turn, in sleeve 236 and thelatter is mains tained in a horizontal position regardless of theangular adjustment of sleeve 44 by means of'upperand lower guide flanges238 slidingly engaging rack 234.

toclr shaft 216 is connected by a universal joint 'to a rock shaft 239journaled at its upper end in a pair of arms 240 formed as an extensionof sleeve 236 so as to move back and forth with sleeve 44 while beingmaintained in a horizontal position by guide flanges 238. Similarly tothe rock shaft 218, the shaft 216 comprises two relatively rotatableparts, of which the lower part carries an arm 242 engaging an arm 244carried by the upper part; and there is fast on the rock shaft 239 atoothed segment 246. Arm 242 operates the segment by direct engagementwith arm 244 when rocked to the right in Fig. 6 and when it is rocked t0the left it operates the segment through a spring 248 surrounding a bolt250 which passes through openings in arms 242 and 244. The bolt isformed with a fixed head seating against arm 242 and with an adjustablehead 252 engaging spring 248.

Segment 246 is in driving engagement with a rack 254 formed on anextension of a sleeve 256 mounted on a reduced portionof the rod orplunger 42. which is operated thereby for opening and closing wipers 30.Sleeve 256 is retained in its place on the reduced end of the rod orplunger 42 by a head 258 and is kept from turning when rod 42 isangularly adjusted with sleeve 44 by guide flanges 260 carried by arms240 which are in sliding engagement with the upper and lower surfaces ofrack 254.

Springs 228 and 248 are quite heavy, as they are not expected to yieldduring the normal operation of the machine. If, however, for any reasonthe wipers do not clear the last bottom before the beginning of theoverwiping operation, these springs can yield to prevent damage.

By this arrangement it will be observed that operation of rock shaft 218for advancing. and retracting the wipers has no effect on the openingand closing. of the wipers, as it merely carries arms 240 and the shaft239 idly back and forth and therefore swings the top of rock shaft216backward and forward without any operative effect upon it and thuswithout affecting the relation of the wipers to each other. On the otherhand, operation of rock shaft 216 is independent of the longitudinalposition of sleeve 44, and operates to open and close the wipers withouthaving any efiect on their advancing and retracting movements. Thedifferent trains of mechanism leading from. the operating shaft to thewipers for advancing and for closing the wipers respectively are thusvoperatively independent of each other; that is, the extent of movementrequired of either train of mechanism properly to perform its lengthwiseof the shoe inthe upwiping op eration has no effect upon the relation ofthe Wipers to each other. The vertical movements of slide 64 have noeffect, either on the closing or the advancing movement of the wipers,due to the use of telescopic shafts and universal joints as parts of theoperating connections. I

.While not limited to such use, a construction such as above describedmay adv-an tageously be modified as illustrated in Fig. 7, or in anequivalent manner, to vary the amount of advancing and closing movementsof the wipers, or so that the amount or rate of closing movement whichcorresponds to a given advancing movement, or vice versa,

may be changed to suit the particular shoe being lasted, So far as I amaware, in all previous machines this ratio has been fixed, and in orderto make such a change it has been necessary to remove some of the partsof the machine and replace them by others. In the embodiment of thisfeature of my in vention illustrated in Fig. 7, bell crank levers 190and 192 are connected to their-respective plungers 196 through links270.. Each of these links is pivotally connected at one end to itsplunger 196 and at theother end to a block 272 threaded on an adjustingdevice 274twhich is carried by lugs 276 and 27 8' on bell crank lever192 (or 190) in such a manner that the adjusting device is restrainedagainst longitudinal movement. Each of the adjusting devices-27 i isformed with a knurled head 280, by means of which it may be manipulated.turning either of the heads 280 the corresponding block 272 is moved upor down to change the effective length of the bell crank lever by whichit is carried, in such a manner as tochange the extent of movement ofplunger 196 corresponding' to the throw imparted to the bell crank leverby its cam 146 or 184.

This arrangement is entirely new so far as I am aware, and is useful inchanging the machine over from welt to McKay work or vice versa,inasmuch as it is necessary to advance the Wipers farther and at thesame time toclose them farther in overwiping Mc Kay shoes thanisnecessary or desirable with 'welt shoes. This novel arrangement 15 ofeven greater utility in adjusting for different sizes and styles of weltshoes or McKay shoes as the case may be. It is desirable to wipe in atopposites ides of the toe of'a shoe, approximately at the ends of thetip seam, substantially the same linear distance as the wiperssimultaneously move forward over the end of the toe, to provide asnearly as possible for uniform wiping action ontirely around the toe.Obviously the amount of angular movement of the wipers neces-, sary toproduce this result, for a given amount of advancing movement, dependsupon how nearly the sides of the toe approach a relation parallel to thelongitudi-v nal median line of the forepart of the shoe, andconsequently a greater angular movement of the wipers is necessary, forthe best results, on some shoes than on others, for example on pointedtoes as compared with round toes. Heretoforc it has been necessary,unless the machine was actually changed over by replacing various parts,to design the machine to impart a definite closing movement to thewipers for each increment of advance, in such amanner as to operate mostefliciently on a shoe of average size and style. his sort of acompromise has been found to work very well on many kinds of work, butdoes not permit of securing the extreme accuracy that is possible withthe abovedescribed arrangement, which provides for adjusting the machinefor each change in the size or style of shoes.

In addition to the above-described adjustments for varying the rate orextent of either the advancing or the closing movement of the wipers,the nuts208 in cooperation with the sleeve 202 and the spring 200 of thewipenadvancing mechanism may be utilized to adjust the Wipers initiallylengthwise of the shoe withoutaffecting their relation to each other,and similarly the corresponding parts of the wiper-closing mechanism maybe utilized to adjust the wipers toward or from each other withoutaffecting their position lengthwise of the shoe.

It is desirable to render springs 200 in effective, during theoverwiping operation, to prevent on the one hand any yielding of wipers30 during that operation, and on the other hand to prevent the springs,which at that time have been tcnsioned by engagement of wipers 30 withthe end and side face-s of the shoe during theupwiping operation, fromprojecting the wipers suddenly inward over the shoe bottom. To attainthese ob jects each of the levers and 192 carries i ea a latch 284 sopositioned as to engage a rack j i 286 carried by sleeve 198, the rackbeing formed to prevent movement of the latch in either direction. Eachlatch 28% is held out of engagement with its rack during the upwipingoperation by a guard member 288 'adjustably secured to casing 214. theguard 'member engaging a pin 290 carried by the latch as shown inFigzfi.At the conclusion of the upwiping operation, the bell crank levers 190and 192 have been rocked forward to such positions that the pins 290ride down lit) to a thinner portion of the guard members 288, thelatches thereby being permitted to engage their racks and lock plungers196 and sleeves 198 together during the overwiping operation, thusrendering springs 200 in effective.

In the operation of the machine described above, a pulled-over shoe andits last are placed in the machine, as shown in dotted lines in Fig. 3,the jacking mechanism is operated, and the heel seat is lasted, all asis usual with machines of the bed luster type. Either before or afterthe lasting; oi? the heel seat, holddown 80 is swung over the tlorwardpart of the shoe bottom and clamped thereagainst by manipulation oftreadle 98. This operation ac s tliirough rack block 112 and link 126 toswing arm 1.28 in such a manner as to vary the etlective length of lever138 according to the vertical height of the shoe bottom. \Vipcrs 30 areadiuste fl by manipulation of handles 52, and G6 to aline them withrespect to the shoe bottom and to position them angularly and lengthwisein proper relation. to the toe, and aiiljusting de vices 274 (Fig. 7)are set it this is necessary. Manipulation of handle 52 operates throughtelescopic shaft 118 to change the position of rack block 112 in such amanner as further to vary the effective length oi lever 138 tocompensate for any change in the vertical position of the wipers.

Treadle 172 is arranged to control the Horton clutch by moving the E armlever 164:

to bring controller 160 or 162 into position to-engage one of the stopsat, b, or a, or to avoid engaging any of the stops, in such a mannerthat if the treadle depressed and immediately released, sl'iatt 14B isturned far enough to operate lever 138 to bring wipers 30 up to aposition a predetermined distance below the shoe bottom, ashereinbeitore explained, to operate levers 190 and 192 to advance thewipers and close them yieldingly about the end oi the shoe, and tooperate lever 180 to raise the wipers to the level oi? the shoe bottomto upwipe the toe under such yielding pressure. whereupon the machinecomes to rest, by reason of the action of the con trollcr 162 on thesecond stop on its clutch disk, to permit arrangement of the uppermaterials prior to the overwiping operation by manipulation of a handpincer or otherwise, and to permit inspection of the work to determineif the wipers are properly positioned in relation to the shoe bottom.Cams 14:6 and 184; are so formed that the remainder of the revolution ofshaft 148 serves further to rock levers 190 and 192 first to wipeinwardly over the shoe bottom to an extreme position. then to withdrawalmost to the edge of theshoe bottom and then again to wipe inwardly totacking or wiring position, and finally to return all the parts to theirinitial positions. Dnringthe overwip ing operation lever 180 is operatedby its cam yieldingly to pull wipers 30 first lightly and then heavilydown againstthe shoe bottom as the wipers move inwardly. to iron theupper materials down upon the shoe bottom, while on each of theretractii'ig movements of the wipers this lever is rocked quickly torelease the pressure on the wipers and to lift them so as to preventthem from dragging the upper materials backwardly. To complete the cyclein this manner, the operator will preferably depress the treadle 172 toits lowest position, and with the treadle held or latched in thisposition the machine will perform the overwiping operations as aboveexplained and the controller 160 will act to stop the machine with thewipers in position to permit the tacking or the wiring of the toe,depending upon whether the shoe is a hilt-Kay shoe or a welt shoe.Release of the treadlc will then cause the parts to return to theirstarting positions. where the machine is stopped by the action of thecontroller 162 on the first abutment of: its clutch disk. The operatorwill then push on the usual knee lever to cause the jacking: mechanismand the holddown to release the shoe.

As an alternative to the above-described manner of operation, theoperator may at any time, if he desires, render the machine continuouslyoperative by moving the treadle to an intermediate position and holdingor latching it in that position. This may be done after the machine hasbeen stopped at the. end of the upwiping operation, in which case thewipers will perform the over wiping operations and will then retract andrepeat their entire cycle of movements, including both the upwiping andthe overwiping operations, as many times as the operator may desire. Byproperly positioning the treadle, the operator may then cause themachine again to come to a stop at the end of the upwiping operation orin position for the tacking or wiring operation. On the other hand, themachine may, at the start, be rendered operative, upon a full depressionoi the treadlc, to pert-arm the upwiping and then the overwipingoperation and to come to a stop in position for tacking or wiring, or bymoving the treadle at once to an intermediate position the machine maybe caused to go through its entire cycle with out a stop and to repeatthe cycle one or more times before coming to a stop in any one of itsnormal stopping positions as may be determined by the ope ator.

It will be observed that the wipers are moved preliminarily by ashoe-controlled device hcightwise of the shoe a distance depending uponthe height of the toe and. which may be different for different shoes,so that they are closed about the end of each shoe a predetermineddistance below the shoe bottom. By this arrangement the upwipingoperation on all shoes is carried out in a predetermined manner Withoutspecial attention from the operator. lVipers 30 are yieldingly, closedabout the end of the shoe after they have been thus positioned and areheld thereagainst during the upwiping operation through the medium ofsprings 200 so that they may adjust themselves to the contour of theshoe, which is different at different levels, and may yield eitherlength-' wise or laterally of the shoe, and at the conclusion of thenpwiping operation they have therefore automaticallybeen adjusted to thecontour of the edge of the shoe bottom. At this time the latches 284operate to render springs 200 ineffective and during the overwipingoperation the Wipers are controlled in a predetermined manner andsubstantially positively by cams 146 and 184, While at the same time theWipers are yieldingly depressed in a predetermined manner by theoperation of cam 184 on lever 180.
